[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a tolerance adjuster 100, which is used to fasten a first component 200 to a second component, and is mainly used in occasions with high requirements for fastening and assembly accuracy, mainly in occasions where the fixed component cannot be installed normally or is installed in an offset position due to the size and positioning errors of the fixing component itself. The tolerance adjuster 100 includes an axial adjustment component 110, a radial adjustment component 120 and a fastener 130.
[0035] See also Figure 4 and Figure 5 , wherein the axial adjustment member 110 is threadedly connected to the first component 200, and the inner circumferential wall of the axial adjustment member 110 is provided with an annular protrusion 111. The outer circumferential wall of one end of the radial adjustment member 120 is provided with an elastic adjustment portion 121, and the elastic adjustment portion 121 abuts against the inner circumferential wall of the axial adjustment member 110, and one end of the radial adjustment member 120 away from the elastic adjustment portion 121 is penetrated by the annular protrusion 111. The radial adjustment member 120 is penetrated by a first fastening hole 122 along its axial direction, and the fastener 130 is penetrated by the first fastening hole 122 and is fastened to the second component.
[0036] The tolerance adjuster 100 provided in the embodiment of the present application is characterized in that the inner circumferential wall of the axial adjusting member 110 is provided with an annular protrusion 111, and the outer circumferential wall of one end of the radial adjusting member 120 is provided with an elastic adjusting member 121 abutting against the inner circumferential wall of the axial adjusting member 110, and the end of the radial adjusting member 120 away from the elastic adjusting member 121 is penetrated through the annular protrusion 111, so that the radial adjusting member 120 can be pre-installed at the axial position of the annular protrusion 111 under the abutment action of the elastic adjusting member 121 and the inner circumferential wall of the axial adjusting member 110, and the radial adjusting member 120 is penetrated by a first fastening hole 122 along its axial direction, and the fastener 130 is penetrated through the first fastening hole 122, so that the fastener 130 pre-installed in the first fastening hole 122 is located at the axial position of the annular protrusion 111.
[0037] When the fastener 130 is not aligned with the second component and the position of the fastener 130 needs to be adjusted in the radial direction, the elastic adjustment portion 121 can be bent under force to absorb the change in displacement, so that the fastener 130 is aligned with the second component, so that the fastener 130 can be passed through the first fastening hole 122 and fastened to the second component, thereby realizing the radial adjustment function of the tolerance adjuster 100.
[0038] At the same time, by threading the axial adjustment member 110 with the first component 200, when the axial adjustment member 110 is rotated, the axial adjustment member 110 can be displaced relative to the first component 200 in the axial direction, thereby driving the radial adjustment member 120 and the fastener 130 to be displaced relative to the first component 200 in the axial direction synchronously, so that the fastener 130 is inserted into the first fastening hole 122 and fastened to the second component, thereby realizing the axial adjustment function of the tolerance adjuster 100. Then, the components to be assembled (the first component 200 and the second component) are finally locked and fixed, so as to realize the automatic adjustment of the tolerance of the components to be assembled.

When installing the hidden door handle, it is required that the installation gap around the hidden door handle is uniform and has a fixed height difference with the outer arc surface of the door sheet metal. Since the door sheet metal has certain production and manufacturing errors in its fastening hole during the production process, in order to eliminate the influence of such errors on the installation accuracy of the hidden door handle, it is necessary to use the tolerance adjuster 100 to adjust the error to meet the installation accuracy requirements.

[0050] Exemplarily, the snap-fit portion 123 may be a buckle.
[0051] In the above-mentioned embodiment of the present application, the radial adjustment member 120 , the elastic adjustment portion 121 and the clamping portion 123 are made by integral injection molding.
[0052] In this embodiment, the radial adjusting member 120, the elastic adjusting portion 121 and the clamping portion 123 are made of one piece by injection molding, which can save the step of installing the elastic adjusting portion 121 and the clamping portion 123 on the radial adjusting member 120, thereby improving the installation efficiency. On the other hand, it can also improve the connection stability and reliability between the radial adjusting member 120, the elastic adjusting portion 121 and the clamping portion 123.
[0053] like Figure 4 and Figure 5 As shown, in the above embodiment of the present application, a plurality of the clamping portions 123 are provided, and the plurality of the clamping portions 123 are arranged at intervals along the outer circumference of the radial adjustment member 120 .
[0054] In this embodiment, by setting the number of the clamping parts 123 to be multiple and arranging the multiple clamping parts 123 at intervals along the outer circumference of the radial adjusting member 120, the installation stability and reliability between the radial adjusting member 120 and the annular protrusion 111 can be further improved, thereby further reducing the probability of the radial adjusting member 120 being separated from the axial adjusting member 110.

At the same time, when the fastener 130 is not aligned with the second component and the position of the fastener 130 needs to be adjusted in the radial direction, the elastic adjustment portion 121 can be bent by force to absorb the change in displacement, so that the fastener 130 is aligned with the second component, so that the fastener 130 can be inserted into the first fastening hole 122 and fastened to the second component, thereby realizing the radial assembly error adjustment, and finally the components to be assembled are locked and fixed, thereby realizing the automatic adjustment of the tolerance of the components to be assembled.
